Sir i need a keil c program for 4x4 matrix keypad or 4x3 keypad matrix interfacing with 8051 displaying output on lcd display through P0 as output port for LCD
Do you really think anyone care about "i need some programs"?
We all "need" things. That doesn't make people all around us suddenly start running around to try to help keep us supplied.
You need to start work yourself. Or hire someone (as in paying for help).
